That looks like a great project. The SS welds look very professional. You saved big bucks on that and should be using it a long time. You want to have a very good ground on the outer tank to minimize the possibility of electrolysis between the 2 different metals. After a year of use check to verify. If it does start, you may find it necessary to remove the galv. tank and build a SS outer tank.
I'm not saying it will occur, just the possibility. The "super" ground suggestion comes from my 25 years experience in Outdoor Wood boilers, they needed HD ground wires to reduce electrolysis between the water jacket, the SS flue tubes and the firebox.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
